part 2. The toy motor to generator project.?

Question

i asked a question regarding converting a toy motor into a generator. turns out it can happen and i got 10 volts AC from it. next question is this single phase and what would i need to charge up a 1.5 volt battery

Answer 1

well your getting ac current and thats not going to charge a dc battery, well at least not safely. you would need to convert the current to dc just like an alternator on a car does. yes it would be single phase

Answer 2

You will need to build a Rectifier circuit, out of 4 power diodes, that will convert the ~~ AC volts to -- DC volts. Basically a rectifier circuit takes 4 diodes, makes a square with them, and pulls off the corners to convert to a pulsing DC. Capacitors are then used to smooth out the waviness for a smooth DC voltage. That's it in a nutshell. You can buy a rectifier probably from a Radio Shack, or get one out of a busted battery charger at a yard sale or flea market. Every electronic device that inputs AC volts has a Rectifier circuit, but it's converting 120 ac to small DC, you've got a small AC, so you'd need a special circuit to get 1.5 DC volts.

The most simple thing to do is to make a half wave rectifier, and use a 1.5 volt rated zenier diode and capacitor as a regulator. The below link may help you.
